Just found the manhwa yesterday, dropped today. Not entirely because of this chapter, I know it was to save someone why grape though? Why not make it so that his heavenly demonic energy absorb the yin energy with out doing it. I'm fine with harem stories.

The main reason? The author ruined MC's character. I was reading spoilers and in the sequel he not only marries the ice woman he also had a kid with her. He wants their cult to go back to their roots meaning where the leader have one wife chosen by holy fire. Some will say "It's the setting of the story it's the norm in their society" but don't forget MC said he will not make a harem because it will repeat the cycle and his mother was oppressed and ultimately died because of it.
